ギア１は、エンジンから伝達された駆動力（回転力）が入力されるとシャフト３を中心として回転可能とされたもので、リベットＲ等によりクラッチハウジング２と連結されている。このクラッチハウジング２は、同図右端側が開口した円筒状のケース部材から成り、その内周壁には複数の駆動側クラッチ板６が取り付けられている。かかる駆動側クラッチ板６のそれぞれは、略円環状に形成された板材から成るとともにクラッチハウジング２の内周面に形成されたスプラインと嵌合することにより、当該クラッチハウジング２の回転と共に回転し、且つ、軸方向（同図中左右方向）に摺動し得るよう構成されている。   The gear 1 is rotatable about the shaft 3 when a driving force (rotational force) transmitted from the engine is input, and is connected to the clutch housing 2 by a rivet R or the like. The clutch housing 2 is formed of a cylindrical case member having an opening on the right end side of the figure, and a plurality of drive side clutch plates 6 are attached to the inner peripheral wall thereof. Each of the drive side clutch plates 6 is made of a plate material formed in a substantially annular shape, and is fitted with a spline formed on the inner peripheral surface of the clutch housing 2, thereby rotating with the rotation of the clutch housing 2, And it is comprised so that it can slide to an axial direction (the left-right direction in the figure).

クラッチ部材４は、クラッチハウジング２内に配設された部材から成るものである。かかるクラッチ部材４の略中央にはシャフト３が貫通しつつスプライン嵌合により当該クラッチ部材４とシャフト３とが連結されており、クラッチ部材４が回転するとシャフト３も回転するよう構成されている。また、クラッチ部材４の外周側面には、その軸方向（同図中左右方向）に延びるスプライン（スプライン嵌合部４ｃ）が形成されており、該スプラインに被動側クラッチ板７が嵌め込まれて取り付けられている。   The clutch member 4 is a member disposed in the clutch housing 2. The clutch member 4 and the shaft 3 are connected to each other by spline fitting while the shaft 3 passes through substantially the center of the clutch member 4, and the shaft 3 is also rotated when the clutch member 4 rotates. Further, a spline (spline fitting portion 4c) extending in the axial direction (left and right direction in the figure) is formed on the outer peripheral side surface of the clutch member 4, and the driven clutch plate 7 is fitted into the spline and attached. It has been.

That is, the clutch plates 6 and 7 are allowed to slide in the axial direction of the clutch member 4 and are pressed against each other when pressed by the pressure member 5 in the left direction in FIG. Is transmitted to the shaft 3 via the clutch member 4, and when the pressure member 5 is released, the pressure contact force is released, the clutch member 4 stops following the rotation of the clutch housing 2, and stops. The rotational force is not transmitted to.

プレッシャ部材５は、クラッチ部材４の軸方向（図１中左右方向）に移動が可能とされつつ当該クラッチ部材４の図中右端側の位置に取り付けられ、クラッチ部材４に対する軸方向への移動に伴い駆動側クラッチ板６と被動側クラッチ板７とを圧接させ又は圧接力を解放させ得るものである。より具体的には、プレッシャ部材５は、クラッチスプリング８により同図中左方向へ常時付勢されるとともに、シャフト３の内部には、その軸方向に延びるプッシュロッド９が配設されており、運転者が図示しないクラッチレバー等の操作手段を操作することにより当該プッシュロッド９を同図中右方向へ突出させ、プレッシャ部材５をクラッチスプリング８の付勢力に抗して右方向（クラッチ部材４から離間する方向）へ移動させることができるようになっている。   The pressure member 5 is attached to a position on the right end side in the drawing of the clutch member 4 while being movable in the axial direction (left and right direction in FIG. 1) of the clutch member 4, and moves in the axial direction with respect to the clutch member 4. Accordingly, the drive side clutch plate 6 and the driven side clutch plate 7 can be brought into pressure contact or the pressure contact force can be released. More specifically, the pressure member 5 is always urged to the left in the figure by the clutch spring 8, and a push rod 9 extending in the axial direction is disposed inside the shaft 3, When the driver operates an operation means such as a clutch lever (not shown), the push rod 9 is protruded rightward in the figure, and the pressure member 5 is moved rightward (clutch member 4 against the urging force of the clutch spring 8). In a direction away from the head).

しかして、プレッシャ部材５が右方向へ移動すると、駆動側クラッチ板６と被動側クラッチ板７との圧接力が解かれ、ギア１及びクラッチハウジング２に入力された回転力がクラッチ部材４及びシャフト３へ伝達されず遮断されることとなる。すなわち、プレッシャ部材５は、クラッチ部材４に対する軸方向への移動に伴い駆動側クラッチ板６と被動側クラッチ板７とを圧接又は圧接力を解放させることができるよう構成されているのである。   Thus, when the pressure member 5 moves to the right, the pressure contact force between the drive side clutch plate 6 and the driven side clutch plate 7 is released, and the rotational force input to the gear 1 and the clutch housing 2 becomes the clutch member 4 and the shaft. 3 is cut off without being transmitted. That is, the pressure member 5 is configured to be able to press the driving side clutch plate 6 and the driven side clutch plate 7 or release the pressing force with the movement of the clutch member 4 in the axial direction.

ところで、クラッチ部材４及びプレッシャ部材５には、図２、３に示すように、所定角度勾配した勾配面から成るクラッチ部材側第１カム面４ａ、クラッチ部材側第２カム面４ｂ、及びプレッシャ部材側第１カム面５ａ、プレッシャ部材側第２カム面５ｂがそれぞれ形成されている。しかるに、クラッチ部材側第１カム面４ａとプレッシャ部材側第１カム面５ａとを対峙させて圧接アシスト用カムを構成するとともに、クラッチ部材側第２カム面４ｂとプレッシャ部材側第２カム面５ｂとを対峙させてバックトルクリミッタ用カムを構成している。   By the way, as shown in FIGS. 2 and 3, the clutch member 4 and the pressure member 5 include a clutch member-side first cam surface 4a, a clutch member-side second cam surface 4b, and a pressure member, each of which has a gradient surface inclined by a predetermined angle. A side first cam surface 5a and a pressure member side second cam surface 5b are formed. However, the clutch member side first cam surface 4a and the pressure member side first cam surface 5a are opposed to each other to form a pressure contact assist cam, and the clutch member side second cam surface 4b and the pressure member side second cam surface 5b. The cam for the back torque limiter is configured by facing each other.

圧接アシスト用カムは、クラッチハウジング２（入力部材）に入力された回転力がシャフト３（出力部材）に伝達され得る状態となったときにプレッシャ部材５及びクラッチ部材４が相対的に回転し、これらプレッシャ部材５及びクラッチ部材４が近接することにより駆動側クラッチ板６と被動側クラッチ板７との圧接力を増加させ得るものである。すなわち、クラッチハウジング２（入力部材）に入力された回転力がシャフト３（出力部材）に伝達され得る状態となったとき、図４に示すように、クラッチ部材４がプレッシャ部材５に対してａ方向に相対的に回転するので、クラッチ部材側第１カム面４ａとプレッシャ部材側第１カム面５ａとが当接し、これらカム面のカムの作用により、プレッシャ部材５をｂ方向に移動させ、駆動側クラッチ板６と被動側クラッチ板７との圧接力を増加させるよう構成されているのである。   In the pressure contact assist cam, when the rotational force input to the clutch housing 2 (input member) can be transmitted to the shaft 3 (output member), the pressure member 5 and the clutch member 4 relatively rotate, When the pressure member 5 and the clutch member 4 come close to each other, the pressure contact force between the driving side clutch plate 6 and the driven side clutch plate 7 can be increased. That is, when the rotational force input to the clutch housing 2 (input member) can be transmitted to the shaft 3 (output member), the clutch member 4 moves a to the pressure member 5 as shown in FIG. Since the clutch member side first cam surface 4a and the pressure member side first cam surface 5a are in contact with each other, the cam of the cam surface moves the pressure member 5 in the direction b. The pressure contact force between the drive side clutch plate 6 and the driven side clutch plate 7 is increased.

バックトルクリミッタ用カムは、シャフト３（出力部材）の回転がクラッチハウジング２（入力部材）の回転数を上回ったときにプレッシャ部材５及びクラッチ部材４が相対的に回転し、これらプレッシャ部材５及びクラッチ部材４が離間することにより駆動側クラッチ板６と被動側クラッチ板７との圧接力の解放を行わせるものである。すなわち、シャフト３（出力部材）の回転がクラッチハウジング２（入力部材）の回転数を上回ったとき、図５に示すように、クラッチ部材４がプレッシャ部材５に対してｃ方向に相対的に回転するので、クラッチ部材側第２カム面４ｂとプレッシャ部材側第２カム面５ｂとが当接し、これらカム面のカムの作用により、プレッシャ部材５をｄ方向に移動させ、駆動側クラッチ板６と被動側クラッチ板７との圧接力を解放させるよう構成されているのである。   In the back torque limiter cam, when the rotation of the shaft 3 (output member) exceeds the rotation speed of the clutch housing 2 (input member), the pressure member 5 and the clutch member 4 rotate relative to each other. When the clutch member 4 is separated, the pressure contact force between the driving side clutch plate 6 and the driven side clutch plate 7 is released. That is, when the rotation of the shaft 3 (output member) exceeds the rotation speed of the clutch housing 2 (input member), the clutch member 4 rotates relative to the pressure member 5 in the c direction as shown in FIG. Therefore, the clutch member-side second cam surface 4b and the pressure member-side second cam surface 5b come into contact with each other, and the cams on these cam surfaces move the pressure member 5 in the d-direction, The pressure contact force with the driven clutch plate 7 is released.

規制部材１０は、所定寸法を超えてプレッシャ部材５がクラッチ部材４に対して離間する方向に移動するのを規制する円環状部材から成るもので、図１に示すように、ボルトＢによりクラッチ部材４と連結され、クラッチスプリング８の一端を受けるよう構成されている。なお、クラッチスプリング８の他端は、プレッシャ部材５の所定部位で受けられており、かかるクラッチスプリング８により、プレッシャ部材５がクラッチ部材４に近接する方向に付勢されることとなる。   The restricting member 10 is formed of an annular member that restricts the pressure member 5 from moving in a direction away from the clutch member 4 beyond a predetermined dimension. As shown in FIG. 4 and is configured to receive one end of the clutch spring 8. The other end of the clutch spring 8 is received at a predetermined portion of the pressure member 5, and the pressure member 5 is urged by the clutch spring 8 in a direction approaching the clutch member 4.

ここで、本実施形態においては、プレッシャ部材５及びクラッチ部材４は、軸方向に嵌合して組み付けられる（すなわち、インローにより組み付けられる）とともに、当該プレッシャ部材５又はクラッチ部材４の嵌合面（α、β）のうち本実施形態においてはプレッシャ部材５の嵌合面βに抵抗部材１１が配設されている。より具体的には、プレッシャ部材５の嵌合面βにおける所定位置には、図３に示すように、取付凹部５ｃが形成されており、その取付凹部５ｃに対して抵抗部材１１が圧入等にて固定されているのである。   Here, in this embodiment, the pressure member 5 and the clutch member 4 are fitted and assembled in the axial direction (that is, assembled by an inlay), and the fitting surface of the pressure member 5 or the clutch member 4 ( Among the α, β), in this embodiment, the resistance member 11 is disposed on the fitting surface β of the pressure member 5. More specifically, as shown in FIG. 3, a mounting recess 5c is formed at a predetermined position on the fitting surface β of the pressure member 5, and the resistance member 11 is press-fitted into the mounting recess 5c. It is fixed.

かかる抵抗部材１１は、プレッシャ部材５がクラッチ部材４に対して相対的に回転する際、当該プレッシャ部材５に対して摺動抵抗を生じさせるものであり、本実施形態においてはゴム材にて構成されている。すなわち、プレッシャ部材５がクラッチ部材４に対して相対的に回転する際、抵抗部材１１がクラッチ部材４の嵌合面αを摺動することとなり、その摺動に伴って摺動抵抗が生じるのである。なお、本実施形態においては、プレッシャ部材５の嵌合面βに抵抗部材１１を配設しているが、クラッチ部材４の嵌合面αに抵抗部材１１を配設するようにしてもよい。   When the pressure member 5 rotates relative to the clutch member 4, the resistance member 11 generates a sliding resistance with respect to the pressure member 5. In the present embodiment, the resistance member 11 is made of a rubber material. Has been. That is, when the pressure member 5 rotates relative to the clutch member 4, the resistance member 11 slides on the fitting surface α of the clutch member 4, and sliding resistance is generated along with the sliding. is there.

A clutch member side second cam surface 4b and a pressure member side second cam surface 5b constituting the cam are respectively formed. In addition, the same code | symbol is attached | subjected to the component similar to 1st Embodiment, and those detailed description is abbreviate | omitted.

ここで、本実施形態においては、プレッシャ部材５及びクラッチ部材４は、軸方向に嵌合して組み付けられる（すなわち、インローにより組み付けられる）とともに、当該プレッシャ部材５又はクラッチ部材４の嵌合面（α、β）のうち本実施形態においてはプレッシャ部材５の嵌合面βに抵抗部材１３が配設されている。より具体的には、プレッシャ部材５の嵌合面βには、図７に示すように、周方向に亘って抵抗部材１３が貼着等により取り付けられているのである。   Here, in this embodiment, the pressure member 5 and the clutch member 4 are fitted and assembled in the axial direction (that is, assembled by an inlay), and the fitting surface of the pressure member 5 or the clutch member 4 ( In this embodiment, the resistance member 13 is disposed on the fitting surface β of the pressure member 5 among α, β).
